Having thus described the invention, what we claim is l. A detachable rubber heel comprising in combination with a metallic plate adapted to be secured to the leather heel of a shoe, inverted substantially T-shaped members secured to the bottom of said plate, channel members in said rubber heel adapted to slidably receive the T-shapedmembers7 means for preventing the accidental displacement of the rubber heel from the leather heel, said means comprising a flatv spring secured to the side of each of the channel members, the forward end thereoie being disposed laterally .to provide a tongue adapt-ed for engagement with the forward ends of the respective T-shaped members, and means in the opposite ends of the channel members for facilitating the detaching of the rubber heel frornthe leather heel when said tongues are moved out of engagement with the forward I ends of the T-shaped members, said last mentioned means comprising coil springs disposed in the rear ends of the channel members and cooperating with the rear ends yof the T-shaped members.

2. A detachable rubber heel comprising 1n combination with a metallic plate adapted to be secured to the leather heel of a shoe, inverted substantially T-shaped members secured to the bottom of the plate,` channel members in said rubber heel adapted to slidably receive the T-shaped members, means for preventing the accidental displacement of the rubber heel from the leather heel, and to further lock the rubber heel in proper position on the leather heel, said means comprising a flat spring secured to the side of each of the channel members, the forward ends of the springs being disposed laterally to provide tongues adapted for engagement with the forward ends of the respective T- shaped members, and means cooperating with the rear ends of the T-shaped members for automatically moving the rubber heel with respect to the leather heel when the spring tongues are move-d out of engagement with the forward ends of the T-sha-ped members to facilitate the removal of the rubber heel.
